Subject: Is this really Sigmoria trimaculata?

Hi,
Searching around I found an older letter that had a yellow-legged black millipede in North Carolina (https://www.whatsthatbug.com/2009/05/03/millipede-3/), but both the letter-writer’s photo and the photos on the Bug Guide page for Sigmoria trimaculata showed yellow markings on the back of the millipede as well (especially the latter!).
The millipede that I found looks completely solid black on the top/back, with only its legs and… leg-plates-joiny-bits?… being yellow. I couldn’t find any Wikipedia page about Sigmoria trimaculata to look up whether this might just be a juvenile, or a subspecies, or something like that — do you know if it is the same species? If so, why is it plain black on top?

Flatbacked Millipede

Dear S.,
We are generally very reluctant to state a Flatbacked Millipede is a definite species, but your individual looks very much like
Apheloria tigana which is pictured on BugGuide where it states:  “‘Apheloria tigana is the dominant xystodesmid millipede in central North Carolina, particularly the “Triangle” (Raleigh, Durham, Chapel Hill region). Individuals typically have yellow paranota (lateral segmental expansions on the dorsa), a yellow middorsal spot on the anterior margin of the collum or 1st segment, and yellow middorsal spots on the caudalmost 3-5 segments. In central NC south of the Deep/Cape Fear Rivers there is a different and undescribed species with yellow middorsal splotches on essentially every segment.’ – Roland Shelley, North Carolina State Museum of Natural Sciences.”

Hi Daniel,
Thank you for the response and the link! I guess they are the sort of
creature where species identification is generally rather tricky? But
that does look exactly like my fella — much appreciated 🙂
Yours,
S

(So in the last two days, I’ve been seeing quite a few of these
critters curled up on the sidewalk in the harsh daylight where I’ve
never seen ’em before, seemingly unable to move even when I nudge them
to a grassy area — not at all like the briskly ambulating specimen
that originally caught my eye. It’s a little worrying. The internet
says millipedes might migrate in spring and fall, but it’s pretty much
already summer hereabouts, and my searches keep coming up 90% about
millipede extermination… sigh…)

Alas, that is because there are far more people want to eliminate lower beasts from their lives than those who want to learn about them.

Millipedes

Dear Coty,
This is not a Worm.  It is a Millipede, possibly a Greenhouse Millipede,
Oxidus gracilis, and according to BugGuide: “Native to Asia, introduced to North America and found throughout the lower 48 states and southern Canada.”  The problem is most likely with the landscaping as this is not an aquatic species.  It is falling into the pool, not living there.

What would be a good insecticide to help knock them down? I keep all the flower beds and grass around it as clean as possible.

We do not provide extermination advice.

My husband found this little fellow along a creek bank in Briceville, TN this evening (04/01/2017). Approximately 3″ in length. Am I correct in identifying it as Sigmoria Trimaculata?

Flat Backed Millipede

Dear John and April,
Alas, we have not the necessary skills to identify this Flat Backed Millipede to the species level.  It certainly might be
Sigmoria trimaculata (please note the first letter of the second word of the species name is lower case), based on this BugGuide image, but it also looks quite similar to this BugGuide image of the Appalachian Mimic Millipedes in the genus Brachoria.  According to BugGuide, the family Xystodesmidae contains many similar looking species.  You might be correct, but we cannot confirm that for certain.

Hi, we recently moved to the Milwaukee area. When we first bought the house I found these ring shaped bug carcass..never any actual bugs. I thought that once we cleaned up (the house had been vacant for awhile) that it would be the end of them. But they keep showing up…not in the kitchen or bathroom, but mostly in the living room. None in the basement…can you tell me what they are? No other signs of critters in the house. Thanks

Millipede Remains

Dear CMM,
We can’t tell from your image if you have found Millipede exoskeletons or the remains of dead Millipedes.  They are generally associated with moist conditions.

Here are my images, but I am unable to load three at a time so I am going to try and send them one by one.
Enjoy!

Millipede Assassin Bugs prey on Millipede

Dear Lollie,
When you submitted a comment to a posting in our archives of Millipede Assassin Bugs preying on a Millipede, we did not imagine that your images were going to be as spectacular as they turned out to be.  They are an excellent addition to our archives.  According to Beetles in the Bush, the Millipede Assassin Bugs
:  “Ectrichodia crux belongs to the subfamily Ectrichodiinae, noted for their aposematic coloration – often red or yellow and black or metallic blue, and as specialist predators of Diplopoda (Heteropteran Systematics Lab @ UCR).  Species in this subfamily are most commonly found in leaf litter, hiding during the day under stones or amongst debris and leaving their shelters at night in search of millipedes (Scholtz and Holm 1985). They are ambush predators that slowly approach their prey before quickly grabbing the millipede and piercing the body with their proboscis, or “beak.”  Saliva containing paralytic toxins and cytolytic enzymes is injected into the body of the millipede to subdue the prey and initiate digestion of the body contents, which are then imbibed by the gregariously feeding assassin bugs.”

Dear Lollie,
Thanks for sending us additional images.  We now have six of your images posted to our site.

Daniel,
The video is still in production.  Will send it as soon as it has been done.

Lollie

Subject: Purple and white millipede
Location: Big Island, Hawaii

Hi,
I was hoping you could help me identify this millipede, which was wandering around on a dirt road at the northern tip of the Big Island, Hawaii. I see lots of rusty millipedes in this area, but this is the first time I’ve seen one like this. It appears to be a purplish color with those broad white stripes along its back. Its antennae are also striped. It’s about an inch long.
I found a couple of photos online, including one on your site (https://www.whatsthatbug.com/2010/01/10/millipede-from-hawaii/), but no ID. Any help would be much appreciated.

Millipede

Dear Graham,
We are not certain your Millipede is the same as the one in our archives, though the markings do look similar.  BugGuide has an unidentified Millipede from Hawaii that looks just like your individual.  We haven’t had any luck finding out anything else.

Thanks for the response. I saw the BugGuide photo too, but since they don’t officially cover Hawaii, their IDs are a bit hit and miss for here. I guess I’ll have to keep looking. I’ll let you know if I get a positive ID.
Mahalo, Graham
